92f180c574 *: log server-side /health checks 
To make it easier to root-cause when /health check fails.
For example, we are using load balancer to health check
each etcd instance, and when one etcd node gets terminated,
it's hard to tell whether etcd "server" was really failing
or client (or load balancer") failed to reach the etcd cluster
which is also failure in load balancer health check.

etcdserver: fix quorum calculation when promoting a learner member 
When promoting a learner member we should not count already a voting
member, but take only into account the number of existing voting
members and their current status (started, unstarted) when taking the
decision whether a learner member can be promoted.

Before this change, it was impossible to grow from a quorum N to a N+1
through promoting a learning member.
